Question 10
A backend API needs a nonstandard HTTP port and the gateway reports connection failures though client port 443 is healthy. An application routes by hostname but uses a generic probe that targets the wrong virtual host and marks every endpoint down. What is the most appropriate plan for this situation?
Explanation
Correct Answer
Frontend and backend ports are independent settings in an application-layer proxy. HTTP virtual hosting can return different health responses depending on the Host header sent by the probe. Both actions are needed.
Incorrect Answers
This plan leaves out a required action: Set the backend HTTP port and probe destination correctly rather than changing the public HTTPS listener. The remaining action alone does not satisfy the situation.
